I have to go with Marco. What is the usual bloat factor between 
C++ and D ? 2x at most ? Unless you found some super efficient 
way of writing a complex grammar, I don't see a reason there 
could be such a large difference.
In fact, for this kind of program, I am not even sure the D code 
will be much smaller than the C++ one overall.
